A farmer story..good one!

A farmer was sitting on his porch one day when a young man drives in and comes to the door.
"Sir, I was driving by and noticed you had a lot of milkweed in your pasture. Would you mind if I went out and got some milk?"
"You don't get milk from milkweed," the farmer replied.
"Oh yes," said the young man, "I have a degree in Agriculture from Texas A&M, I know all about it."
"Well, help yourself," said the farmer.
He soon saw the young man coming back to his car with two buckets full of milk.
The next day the farmer was again sitting on his porch when the same young man drove up.
"Sir, yesterday when I was getting milk, I noticed you had some honeysuckle in the fence row. I wondered if you would mind if I got some honey?"
"You don't get honey from honeysuckle," said the farmer.
Again, the young man explained about his degree from A&M, so the farmer agreed to let him collect some honey. Soon the young man came back to his car with two buckets full of honey.
The next day the same young man drove up to the farmer's house.
"Sir, yesterday when I was getting the honey, I noticed you had some pussy willows down by the creek."
The farmer said, "Let me get my shoes and I'll go with you....."
